Function run_output_device

pub fn run_output_device<C>(
    params: OutputDeviceParameters,
    data_callback: C,
) -> Result<OutputDevice, Box<dyn Error>> 
where
    C: FnMut(&mut [f32]) + Send + 'static,

Available on crate features dep_tinyaudio and alloc only.

Creates a new output device that uses default audio output device of your operating system to play the samples produced by the specified data_callback. The callback will be called periodically to generate another portion of samples.

Examples

The following examples plays a 440 Hz sine wave for 5 seconds.

let params = OutputDeviceParameters {
    channels_count: 2,
    sample_rate: 44100,
    channel_sample_count: 4410,
};

let _device = run_output_device(params, {
    let mut clock = 0f32;
    move |data| {
        for samples in data.chunks_mut(params.channels_count) {
            clock = (clock + 1.0) % params.sample_rate as f32;
            let value =
                (clock * 440.0 * 2.0 * std::f32::consts::PI / params.sample_rate as f32).sin();
            for sample in samples {
                *sample = value;
            }
        }
    }
})
